Le diméthoxyethane, également connu sous les noms de glyme, monoglyme, diméthyl glycol, éthylène glycol diméthyl éther, diméthyl cellosolve et DME , est un liquide clair, incolore, de la famille des éther-oxydes, utilisé comme solvant. Aller à Applications as solvent and ligand – Together with a high-permittivity solvent (e.g. propylene carbonate), dimethoxyethane is used as the low-viscosity component of the solvent for electrolytes of lithium batteries. In the laboratory, DME is used as a coordinating solvent.
Dimethoxyethane is often used as a . L in stainless steel drum.
View returnable container options. Solvent , formula, MW, boiling point (°C), melting point. Generally, these techniques are either economically or environmentally unfavourable because of the use of toxic solvents and considerable heating and pressurizing. Recently, a new extraction technique involving the use of liquefied dimethyl ether ( DME ) as a green solvent has attracted tremendous attention.
The role of passive films in aqueous solutions has been studied extensively (1), while the passivity . Subsequently, remaining non-coordinated solvent can be removed under vacuum until a minimum pressure of 0. Work-up of the mother liquor yields another crop of crystals.
Formulations often contain a blend of slow and medium evaporation rate solvents to optimise the film properties and thus the final appearance. Evaporation rate can affect the drying time of the coatings or inks as well as the film appearance and durability. The evaporation profiles of Dipropylene glycol DME and Diethylene . Until one year ago this solvent was only available in big tanks, for factories specialized in extracting organic materials mainly for the food and cosmetics industry. DME makes mold cleaner and saver to give you the absolute best out of your injection mold supplies. When you buy a quality product from DME , you want to make sure that the product maintains its high standards.
With a mold cleaner or saver from DME , you reduce overall cost for your company, because your product lasts . Cyclopentadiene is not very water soluble and would immediately acquire a proton from a water or alcohol in a protic solvent. FeClwould not be very soluble in a hydrocarbon or halocarbon,. Sta-Sol solvent systems are also used straight as solvent replacements for many resin removal, general cleaning and stripping applications, and coating formulations.
The descriptions “dimethyl esters” ( DME ) and “dibasic esters” ( DBE) are used interchangeably. Institut de Cibncia de Materials de Barcelona (CSIC) and. Departament de Quimica, Universitat Autonoma de. SoDoEx Organic Solvent DME Extraction.

Then there are the solvents I think of as cousins to the main ones. The lesser- used ethers, like dimethoxyethane ( DME ) and dioxane are an example. Solvent power of alkanes for heavy oil increases with higher number of carbon atoms, and ethyl ether had slightly stronger solvent power than heptane.
